Abstract

Introduction: Insufficient sleep durations, irregular sleep patterns, and poor sleep quality predict obesity including adverse changes to obesity-related outcomes like decreased physical activity (PA). In turn, increasing PA positively impacts sleep durations and quality. The transition from childhood to adolescence brings a decrease in PA with females showing a more significant decrease. This decrease in PA may be a contributing factor to the high rates of insufficient sleep and irregular sleep patterns in teens. To better understand these connections, we examined how PA influenced sleep duration and quality in teens. We expected that higher PA durations would predict longer sleep durations, more regular sleep patterns, and better sleep efficiency. We also explored sex differences to better understand how these connections play out during adolescence.

Conclusions: Our analysis showed higher PA predicted longer sleep duration in males. These data provide further support for sex driven differences in how sleep contributes to obesity. Further study with a larger sample is warranted to better understand sex differences in the connection between sleep and obesity.

Sex Differences in the Effect of Physical Activity on Teen Sleep Patterns
